If you aren't sure what the latest battle to the death in the RTS series is about, publisher THQ has released a new trailer that explains the motivation for war starring a number of characters in the stand-alone expansion to help explain the situation. Basically, kill everyone that isn't on your side.

It goes without saying that the game looks nothing like the trailer; however, based on our recent time with the game and in interviewing its producer Jeff Lydell, we're of the mind that it could be just as intense.

Also intense? Multiple pre-order bonuses based on where the game is pre-purchased. But this is more of the burning in the pit of our gut kind of intense.
